Table 1. Minimum and maximum power supply support
When deciding on which and how many power supplies to configure for a 5400zl series switch, the
following criteria can be used to guide the decision:
• How much power will be required for each PoE port, full (15.4 watts) or phone (8 watts) power?
• How many network devices will require power (how many PoE ports are needed)?
• Is redundant power required (for internal power and/or PoE power)?
Note that the power supplies provide a "pool" of power for all line interface modules to draw from;
that is, PoE power is not limited on a per line interface module basis.

Table 2. Examples of maximum number of PoE ports for 5406zl switch
* 5406zl switch fully loaded with 6 modules provides up to 144 ports
** Using the HP ProCurve Switch zl Power Supply Shelf
The table above shows examples of the maximum number of PoE ports that can be supported by the
5406zl switch. One section shows the maximum number of PoE ports at full power (Class 0 – 15.4
watts), and the next section shows the maximum number of PoE ports at phone power (8 watts) for
each configuration. These categories are further subdivided based on whether a second internal power
supply is used to provide power redundancy in the event one of the power supplies fails.
